SPECIFICATION forming part of Letters Patent No. 786,606, dated April ll, 1905.

Application led November 25, 1904. Serial No. 234,315.

T0 all wlwnt it ntctg/ concern.-

Be it known that we, GEORGE SCHWARZ, residing at Brooklyn, in the county of Kings and State of New York, and GEORGE Lowa, re-

5 siding at Jersey City, in the county of Hudson and State of New Jersey, citizens of the United States, have invented new and useful Improvements in Cutting-Sticks, of which the following' is a specilication.

Our invention pertains to a cutting-stick` rf. c., a stick designed to be carried by one of the cutting-rollers of a web-printing press, so as to support a web of paper and receive the cutting edge of a knife on a complementary 5 cutting-roller, with a view of enabling the said knife to make a clean cut; and 'it has for one of its objects to provide a cuttingstick and means coacting with the cuttingstick whereby the stick may be quickly and easily connected to its roller and as expeditiously disconnected and removed therefrom when necessity demands.

Another object of the invention is the provision of a cutting-stick embodying such a construction that the necessity of employing nails or the like to connect the cushion to a backing-bar is obviated, this being advantag'eous, since it renders feasible the employment of an economical composition cushion and also because it permits of the cushion being readily connected to and disconnected from the backing-bar- Another object is to provide a cutting-stick the cushion of which may be conveniently reversed and its usefulness thereby materially prolonged.

With the foregoing in mind the invention will be fully understood Jfrom the following description and claims when taken in connection with the accompanying drawings, forming part of this specification, in which- Figure l is a longitudinal sectional view, partly in dotted lines, illustrating one of the two cutting-rollers of a web-printing press and the cutting-stick constituting the present embodiment of our invention in proper position in said roller. Fig. 2 is a perspective view of the cutting-stick per s@ removed.

Fig. 3 is a similar view of the cushion removed from the stick, and Fig. 4 is a transverse section taken through the stick.

vSimilar letters designate corresponding' parts in all of the views of the drawings, referring to which- A (see dotted lines in Fig. 1)-is one of the cutting-rollers of a web-printing press, in thc perimeter of which the usual longitudinal channel a is provided.

B is a resilient keeper having a beveled head the said keeper being' disposed at the inner side of the thickness of the hollow roller and connected to the same through the medium of bolts c or other suitable means, and C is my novel stick asa whole, which stick is of a shape and size to rest in the channel o of the roller A. The said stick comprises a backing-bar d, preferably of wood, having a head c at one end designed to take into a complementary socket f in the roller A, side bars g, fixed with respect to the backing-bar (Z and having longitudinal ribs /t on their inner sides, a cushion t', preferably of inexpensive colnposition, removably arranged in the holder formed by the bars (Z and g and having correspondingly-shaped grooves j in its opposite sides to receive the ribs /t of bars g, and a resilient latch 7c, connected to an extended end d of the backing-bar (l, shaped to straddle the end of the thickness of the roller A and terminating in an arm having a beveled hcad arranged to engage the head 7) of the keeper B.

In virtue of the construction described it will be observed that when the cutting-stick is slid endwise into the channel t of the roller A the headZ of latch will spring into engagement with the head L of the keeper B, and thereby securely fasten the cutting-stick in the roller, also that when it is desired to remove the cutting-stick from the roller the pressman has but to press the headb of keeper B out of engagement with the head Z of latch and draw the cutting-stick endwise from the channel a. The expedition with which the cutting-stick may be secured in and detached from the roller A will be appreciated as an important advantage when 1t 1s remembered that the cutting-stiel; can only be removed trom and placed in the roller A While the press is idle.

The manner described et' securing the cushion t' in the heldere-v". e., through 'the medium of the coacting grooves 7' and ribs /L--is materially advantageous because it obviates the necessity et using' nails or the like to secure the cushion in the holder, this rendering it 'feasible to make the cushion of a composition much cheaper than rubber, because it permits of the cushion being readily reversed, so as to present a fresh surface to the knife, which materially prolongs the usefulness of the cushion, and because it adapts the cushion to be quickly and easily removed from the holder and as readily replaced with a new cushion when necessary.

It will be gathered 'trom the foregoing that our novel cutting-stiel( as a whole is adapted to be placed and secured in a cutting-roller and disconnected and removed therefrom and that the cushion is adapted to be secured in and removed from the holder without entailing the employment o't tools ot any kind. lt will also be gathered that the cutting-stick is simple, compact, and inexpensive and embodies no delicate parts, such as are likely to get out ot order after a short period ot use.

We have speciiieally described the construction and relative arrangement of the parts embraced in the present and preferred embodiment of our Vinvention in order to impart a l`ull, clear, and exact understanding` ol the said embodiment. Vtfe do not desire, however, to be understood as continingourselves to the said specitic construction and relative arrangement o'f parts, as such changes or modilieations maybe made in practice as `fairly tall within the scope oi our invention as claimed.

Having described our invention, what we claim, and desire to secure by Letters Patent, is

l. rlhe combination olI a cutting-rollerhaving a longitudinal channel in its perimeter extending to one of its ends, a cutting-stick arranged in said channel and removable endwise therefrom, means on the roller, and means on the cutter-stick arranged to engage the lirstmentioned means when the cutter-stick is shoved home and coact with said means to hold the cutter-stick against casual endwise movement. l

2. The combination of acutting-roller having a longitudinal channel in its perimeter extending to one ol its ends, a cutting-stick arranged in said channel and removable endvvise therefrom, said cutting-stick comprising a reaeoe holder open at one end and having a backingbar and side bars provided with longitudinal ribs, and a cushion removable endwise from the holder and having longitudinal grooves disposed midway between its opposite faces and receiving the ribs ot' the holder, means on the roller, and means on the holder of the cutterstick arranged to engage the iirst-mentioned means when the cutter-stick is shoved home and coact with said means to hold the cutter-stick against casual endwise movement.

3. The combination or' a cutting-roller having a longitudinal channel in its perimeter eX- tending to one ot' its ends and also having a socket at the opposite end ot said channel, a cutting-stick arranged in said channel and removable endWise therefrom; said cutting'- sticlt comprising a holder open at one end and having' a head at its opposite end disposed in the socket of the roller, a cushion removable endwise from the holder, and coacting means on the holder and cushion for holding the latter against lateral movement from the `former, means on the roller, and means on the cutterstick arranged to engage the Erst-mentioned means when the cutter-stiel; is shoved home and coact with said means to hold the cutterstick against casual endwise movement.

4L. The combination ot' a cutting-roller havinga longitudinal channel in its perimeter,and also having a beveled keeper at the inner side ot' its thickness, anda cutting-stiel; removably arranged in the channel of the roller and having a latch arranged to engage the keeper on the roller.

5. The combination otl a cutting rellena cutting-stick carried thereby, and afastener comprising members on the roller and stick; one ot' the said members being' arranged and adapted to be sprung into and out of engagement With the other.

6. The combination of a cutting-roller having` a longitudinal channel in its perimeter, a resilient keeper carried by the roller at the inner side of the thicln'iess thereof and having a beveled head, and acutting-stick removably ,arranged in the channel of the roller and having a resilient latch provided with a beveled head arranged to engage that of the keeper. ln testimony whereof we have hereunto set our hands in presence ot' two subscribing Witnesses.
